Berglas virkning

The Genii Berglas issue was a treasure. Allow me to add some perspective to the Berglas mythology. Over the past five or six years there has been a snowballing interest in Any Card at Any Number. Prior to that, however, I don't believe it had any formal name. It was merely something people had seen him do, "you know, that thing he does with cards and the number." Over time it became known simply as "The Berglas Effect."
